**ACTION :**  Final rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Arizona to address the requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA) for the 2008 Lead (Pb) and 2008 ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each State adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. We refer to such SIP revisions as ‘‘infrastructure’’ SIPs because they are intended to address basic structural SIP requirements for new or revised NAAQS including, but not limited to, legal authority, regulatory structure, resources, permit programs, monitoring, and modeling necessary to assure attainment and maintenance of the standards. In addition, we are approving several state provisions addressing CAA conflict of interest and monitoring requirements into the Arizona SIP.

**DATES :**  This final rule is effective on September 9, 2015.

Although ADEQ did not submit an analysis of Section 110(a)(2)(G) requirements, we discuss them in our TSD, which is in the docket for this rulemaking. Table of Contents
I. Background II. EPA’s Response to Comments III. Final Action IV. Incorporation by Reference V. Statutory and Executive Order Reviews I. Background

CAA section 110(a)(1) requires each state to submit to EPA, within three years after the promulgation of a primary or secondary NAAQS or any revision thereof, an infrastructure SIP revision that provides for the implementation, maintenance, and enforcement of such NAAQS. Section 110(a)(2) sets the content requirements of such a plan, which generally relate to the information and authorities, compliance assurances, procedural requirements, and control measures that constitute the ‘‘infrastructure’’ of a state’s air quality management program. These infrastructure SIP elements required by section 110(a)(2) are as follows:

• Section 110(a)(2)(A): Emission limits and other control measures.

• Section 110(a)(2)(B): Ambient air quality monitoring/data system.

• Section 110(a)(2)(C): Program for enforcement of control measures and regulation of new and modified stationary sources.

• Section 110(a)(2)(D)(i): Interstate pollution transport.

• Section 110(a)(2)(D)(ii): Interstate and international pollution abatement.

• Section 110(a)(2)(E): Adequate resources and authority, conflict of interest, and oversight of local and regional government agencies.

• Section 110(a)(2)(F): Stationary source monitoring and reporting.

• Section 110(a)(2)(G): Emergency episodes.

• Section 110(a)(2)(H): SIP revisions.

• Section 110(a)(2)(J): Consultation with government officials, public notification, PSD, and visibility protection.

• Section 110(a)(2)(K): Air quality modeling and submittal of modeling data.

• Section 110(a)(2)(L): Permitting fees.

• Section 110(a)(2)(M): Consultation/ participation by affected local entities.

Two elements identified in section110(a)(2) are not governed by the threeyear submittal deadline of section 110(a)(1) and are therefore not addressed in this action. These two elements are: (i) Section 110(a)(2)(C) to the extent it refers to permit programs required under part D (nonattainment NSR), and (ii) section 110(a)(2)(I), pertaining to the nonattainment planning requirements of part D. As a result, this action does not address infrastructure for the nonattainment NSR portion of section 110(a)(2)(C) or the whole of section 110(a)(2)(I).

On November 12, 2008, the U.S. Environmental Protection Agency (EPA) issued a revised NAAQS for Pb. 1 That action triggered a requirement for states to submit an infrastructure SIP to address the applicable requirements of section 110(a)(2) within three years of issuance of the revised NAAQS. On October 14, 2011, EPA issued ‘‘Guidance on Section 110 Infrastructure SIPs for the 2008 Pb NAAQS’’, referred to herein as EPA’s 2011 Pb Guidance. 2 Depending on the timing of a given submittal, some states relied on the earlier draft version of this guidance, referred to herein as EPA’s 2011 Draft Pb Guidance. 3 EPA issued additional guidance on infrastructure SIPs on September 13, 2013. 4

On March 27, 2008, EPA issued a revised NAAQS for 8-hour Ozone. 5 That action triggered a requirement for states to submit an infrastructure SIP to address the applicable requirements of section 110(a)(2) within three years of issuance of the revised NAAQS. EPA did not, however, prepare guidance at that time for states in submitting I–SIP revisions for the 2008 Ozone NAAQS. 6 On September 13, 2013, EPA issued ‘‘Guidance of Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2),’’ which provides advice on the development of infrastructure SIPs for the 2008 ozone NAAQS (among other pollutants) as well as infrastructure SIPs for new or revised NAAQS promulgated in the future. 7 The Arizona Department of Environmental Quality (ADEQ) has submitted several infrastructure SIP revisions pursuant to EPA’s promulgation of the NAAQS addressed by this rule, including the following:

• October 14, 2011—‘‘Arizona State Implementation Plan Revision under Clean Air Act Section 110(a)(1) and (2); 2008 Lead NAAQS,’’ to address all of the CAA section 110(a)(2) requirements, except for section 110(a)(2)(G), 8 for the 2008 Pb NAAQS (2011 Pb I–SIP Submittal).

• December 27, 2012—‘‘Arizona State Implementation Plan Revision under Clean Air Act Section 110(a)(1) and (2); 2008 8-hour Ozone NAAQS,’’ to address all of the CAA section 110(a)(2) requirements for the 2008 8-hour Ozone NAAQS (2012 Ozone I–SIP Submittal).

• December 6, 2013—‘‘Submittal of Maricopa County Rule 100 revising the Maricopa County Portion of the Arizona State Implementation Plan for Section 110(a)(2) Infrastructure’’ from Eric Massey, Director of ADEQ (2013 Maricopa County Submittal). Maricopa County Rule 100 was submitted to address a deficiency in section 110(a)(2)(E)(ii) of the SIP for Maricopa County concerning conflict of interest requirements for hearing boards.

• December 19, 2013—‘‘Submittal of Pima County Rules revising the Pima County Portion of the Arizona State Implementation Plan for Section 110(a)(2) Infrastructure’’ from Eric Massey, Director of ADEQ (2013 Pima County Submittal). This submittal included Pima County Rule 17.04.190 ‘‘Composition,’’ adopted September 28, 1993; Pima County Rule 17.12.040 ‘‘Reporting for Compliance Evaluations,’’ adopted September 28, 1993; and Pima County Rule 17.24.040 ‘‘Reporting Requirements,’’ adopted April 19, 2005 for inclusion into the Arizona SIP. These rules were submitted to address deficiencies in section 110(a)(2)(E)(ii) of the SIP concerning conflict of interest requirements for hearing boards and section 110(a)(2)(F) of the SIP concerning stationary source monitoring and reporting.


### 47861 Federal Register / Vol. 80, No. 153 / Monday, August 10, 2015 / Rules and Regulations

9 Copies of these Arizona county regulations are included in the 2013 Pima County and Maricopa County Submittals, and 2014 Pinal County Submittal, which are available in the docket for this action and online at http://regulations.gov, docket number EPA–R09–OAR–2014–0258.

• September 4, 2014—‘‘Submittal of Pinal County Rule 1–3–140 Revising the Pinal County Portion of the Arizona State Implementation Plan for Section 110(a)(2) Infrastructure’’ from Eric Massey, Director of ADEQ (2014 Pinal County Submittal). This submittal included Pinal County Rule 1–3–140 ‘‘Definitions,’’ adopted July 23, 2014 for inclusion into the Arizona SIP. Pinal County Rule 1–3–140 was submitted to address a deficiency in section 110(a)(2)(E)(ii) of the SIP for Pinal County concerning conflict of interest requirements for hearing boards.
II. EPA’s Response to Comments

The public comment period on EPA’s proposed rule opened on November 24, 2014, the date of its publication in the Federal Register at 79 FR 69796, and closed on December 24, 2014. During that period, EPA did not receive any
comments.

III. Final Action

Under CAA section 110(k)(3) and based on the evaluation and rationale presented in the proposed rule, the technical support document and this final rule, EPA is approving the 2011 Pb I–SIP Submittal, the 2012 Ozone I–SIP Submittal, the 2013 Maricopa County Submittal, the 2013 Pima County Submittal and the 2014 Pinal County Submittal with respect to the following infrastructure SIP requirements:

• Section 110(a)(2)(A): Emission limits and other control measures.

• Section 110(a)(2)(B): Ambient air quality monitoring/data system.

• Section 110(a)(2)(E): Adequate resources and authority, conflict of interest, and oversight of local and regional government agencies.

• Section 110(a)(2)(F): Stationary source monitoring and reporting.

• Section 110(a)(2)(G): Emergency episodes.

• Section 110(a)(2)(H): SIP revisions.

• Section 110(a)(2)(L): Permitting fees.

• Section 110(a)(2)(M): Consultation/ participation by affected local entities.

In addition, we are approving into the SIP certain regulatory provisions included in the 2013 Pima County and Maricopa County Submittals, and in the 2014 Pinal County Submittal, as discussed in the TSD. 9

We are not acting today on those elements of the infrastructure SIP that address the requirements of sections 110(a)(2)(C), (D), (J) and (K) of the Act. On October 29, 2012, ADEQ submitted ‘‘New Source Review State Implementation Plan Submission’’ and on July 2, 2014 submitted ‘‘Supplemental Information to 2012 New Source Review State Implementation Plan Submission’’. These submissions address the permitting portions of I–SIP elements in sections 110(a)(2)(C), (D), (J) and (K) of the Act and will be addressed in a subsequent rulemaking.

Section 110(l) of the Act prohibits EPA from approving any SIP revision that would interfere with any applicable requirement concerning attainment and reasonable further progress (RFP) or any other applicable requirement of the Act. All of the elements of the infrastructure SIP that we are approving, as explained in the TSD, improve the SIP by replacing obsolete statutes or regulations and by updating the state and local agencies’ SIP implementation and enforcement authorities. We have determined that our approval of the elements discussed above complies with CAA section 110(l) because the SIP revision would not interfere with the on-going process for ensuring that requirements for RFP and attainment of the NAAQS are met, and the SIP revision clarifies and updates the SIP. Our TSD contains a more detailed discussion of our evaluation. IV. Incorporation by Reference

In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference of the Arizona Regulations described in the amendments to 40 CFR part 52 set forth below. The EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the appropriate EPA office (see the **ADDRESSES** section of this preamble for more information). V. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq. );

• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4);

• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and

• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Final rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is approving a May 11, 2012 State Implementation Plan (SIP) submission from the State of Colorado that is intended to demonstrate that its SIP meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2006 fine particulate matter (PM2.5 ) National Ambient Air Quality Standards (NAAQS). This submission addresses the requirement that Colorado’s SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. EPA is determining that Colorado’s existing SIP contains adequate provisions to ensure that air emissions in Colorado do not significantly contribute to nonattainment or interfere with maintenance of the 2006 24-hour PM2.5 NAAQS in any other state, or interfere with another state’s measures to prevent significant deterioration of air quality or to protect visibility. EPA is also approving the portion of Colorado’s submission that addresses the CAA requirement that SIPs contain adequate provisions related to interstate and international pollution abatement.
